SPECIFICATION forming part of Letters Patent No. 326,283, dated September 15, 1885.

Application filed November 13, 1884. (No model.)

To all whom it may concern j Be it known that I, FRANZ .A. FAY, of

Brooklyn, county of Kings, and State of New" York, haveinvented certain new and useful Inn-5 provements in Machinesfor Making Shackle-i WVires for Metallic Seals, of which the follow' ing is a specification.

The object of this invention is to furnish a simple and effective machine for making wire shackles for the metallic seals for which Letters Patent of the United States have been granted to E. J. Brooks under date of June 27, 1876, No. 179,261; and the invention consists of two pairs of rollers, which are arranged vertically above each other and provided at two or more portions of their circumference with edge grooves for the wire, and at the intermediate portions with alternatingindentations and proj ections, that intermesh with the projections and indentations of the other rolls. The wire to be formed is fed from the shaping-rolls to cutting-knives which rotate at the same speed as the shaping-rolls, so as to cut off the proper length of shackle.

In the accompanying drawings, Figure 1 represents a plan of my improved machine for making wire shackles for metallic seals. Fig. 2 is a vertical longitudinal section of the same on line 00 m, Fig. 1. Figs. 3, 4, and 5 are a side view, a vertical transverse section, and a plan of the shaping-rolls, drawn on a larger scale; and Fig. 6, an enlarged side view of a shackle-wire made on the machine.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A A represent the supporting-standards of my improved ma chine for making shackles for metallic seals. A A are shorter standards arranged intermediately between the standards A A, for supporting the driving-shaft B of the machine. A gear-wheel, b, on the driving-shaft B meshes with gear-wheels b,of equal size,on two lower shafts, G O, which are supported in bearings of the standards A A. The gear-wheels b of the lower shafts, O C, mesh with gear-wheels N, of equal size with the wheels 0, on the upper shafts, D D, which are supported in bearings of the standards A A vertically above the shafts O C. By the intermeshing of the gearwheels I) b b b b the same speed is imparte to the shafts O O and D D. r

' To each shaft 0 and D is applied a pair of shaping-rolls, E E, all of the same size, while to the shafts OD are applied the radial cutters F F, which latter are provided with latorally-beveled cutting-edges, as shown in "Fig. 2.

The wire from which the shackle-wires are made is guided from a suitable reel through a fixed guide-eye, g, of one of the standards A, first to the shaping-rolls E E, then from the same through a horizontal guidetube, g, through between the cutting-knives F F, by which the shackle-wires are cut off and dropped onto an inclined delivery-spout, g". The intermediate horizontal tube, g,is supported on a bracket, 9, that is attached to one of the standards A A, as shown clearly in Figs. 1 and 2. The guidetube g is arranged in line with the shaping-rolls E E and the cuttingknives F F. The distance between the shaping-rolls E E and the cutting-knives F F is so arranged that for each revolution of the shaping-rolls andcutting-knives one shacklewire is completed and cut off. 1

The four shaping-rolls E E are so constructed with alternating projections and indentations at portions of their circumference that the shackle-wire shown in Fig. 6 is produced thereby. The shaping-rolls are shown in de tail in Figs. 3, 4, and 5, and are arranged in two pairs, one pair being located on the lower shaft, 0, the other pair vertically above the same on the upper shaft, D. The rollers of each pair are arranged sidewise of each other. The circumference of the rolls E E is equal to the length of the shackle-wire to be made, the rolls being provided at those parts of their circumference where the indentations are to be formed in the shackle-wire with alternating depressions a and projections a, which extend across the width of the rolls in such a manner that they mesh with the projections 11 and depressions a of the adjoining rolls and of the other pair of rolls. The remaining portions of the circumference of the rolls,which are not provided with alternating projections and depressions,are grooved at their adjoining edges toa depth corresponding to one-half the thickness of the wire. By the edge grooves a of the four shaping-rolls the wire is guided and moved forward by the rotation of the rolls. The toothed portions of the rolls feed the wire [0 wires had been shaped, so that they had to be replaced by new ones. To overcome this objection theshaping-rolls are arranged in pairs, each being provided with a circumferential ring of steel, 1). Into the adjoining faces of [5 the rings the edge grooves a for the wire, as

well as the alternating projections a and indentations a, or toothed portions,are out, which are extended across the width of the rolls.

This arrangement has the advantage that on the wearing out of the projections and indentations the rolls can be removed from the shafts and recut by filing off the circumferential steel rings of the rolls. This is repeatedly done at one side of the steel rings of the rolls :5 until the steel rings are flush'with the web I),

after which the rolls are reversed and the alternating projections and indentations cut into the opposite side of the rings, so that this side can be used until it is entirely worn off,

,0 after which the rolls are thrown away, having performed their function. By this arrangement it is possible to use the same set of rolls for making a large number of wire shackles of the type described without the heavy ex- 5 pense for new steel rolls.

for metallic seals, a shaping-roll consisting of a web and a circumferential steel ring, being grooved at two or more portions of its circu n1- ference with edge grooves, and at the intermediate portions with alternating projections and depressions, substantially as set forth.

3. The combination of four shaping-rolls, arranged in pairs and provided with edge grooves at two-or more parts, and with alternating projections and depressions at intermediate portions of its circumference, with an intermediate guide-tube and rotating cutters, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
